The famed @MBTweetFleet tweets using Arduino

In case you have been following MBTweetFleet and availing awesome parking spaces, you would be happy to know that the service was made using an Arduino and GPS/GPRS shield.

The cars automatically generated a tweet with GPS data out of every empty parking space they passed. Via Arduino the onboard electronics were connected to a GPS/GPRS-Shield. Tweets were generated with a PHP Relay which sent the GPS-Data. This is how people could find empty parking spaces near them on twitter and even be navigated there by a linked Google map
